Referring to the 'drawings v in 'detail a .pair 'of spaced parallel wellpipes ill and I2 are provided adjacent their lower ends with pumpingcylinders M 'and 'F6 respectively. The lower ends fof -lthe pumpingcylinders 14 and" |16 are respectively `eqlipl'iel with foot valves |8and 2 0 which are disposed adjaoent the bottoni 'oi the 'well 'and belowtll'e water level therein s'o that s V'the 'pistons v within iii-eeyliiiderslc reciprocate Wa-- ter will be drawn into the cylindersthrough the fro-Qt valves. Whileit is mit absolutely "essential theoperation o i the device it is pieierredthat "the root Vvalves 18 and 26be or the tall c liek ltype lflvil'g springs which advance the ballsagainst the 'valve seats. A

Carried bythe upper ends or 'the well vpipes ip and 'l2 are upperpumping cylinders l22 and i254 respectively, the upper `'ends ofwhichopen into a "Gap 256 having a b'o'tt'ono 2'8 which entends bett/eenthe cyilnd'ers 22 and 24 and 7f orms asl 'p portiera "bearing "3 0 thepurpose of which will b 'llibre hiele'aflel described. Muiltd fT rockingnlotion in 'the bearing '30 is a spherical bearing inc rilber =3 2carrying oppositely 'extend-v ing arl'lls 31! and 136, the ends ofwhichreinote from the bearing member 32 y'are pivotally coluplea topiston rods `all and Aim respectively which Ain turn are vrespe'ctivelyconnected to pistons 'E2 and i4 which work respectively in 'thecylinders .22 and Zas will be readily understood uponlee erenc'ejtb Fig.l. A radially extending arm A6 is carried by the bearing member 3.2 'andis colln'ected through a 'suitable link 48 to lever TBD which ispivotally supported at 52 o'n a bracket 54 carried by th'e cover 26. It'will thus "b'e 'seen that as the lever '50 ismOVe'd about its pivot'152, the arm if will be cscillared thereby 'causing the. bearing Member32 and 'arms S ll'd 3'6 t0 "O'S'l` late in the manner of a walking beam.

Carried by and extending between the lower cylinders i4 and I6 is abearing 56 in which a bearing member of spherical formation 58 ismounted to oscillate. Like the bearing member 32, the bearing member 53is provided with oppositely extending arms EI) and 62 which move inarcuate paths within cylinders I4 and I6 respectively and are connectedthrough the inedium of connecting rods 64 and 66 with pistons 68 and 'I0which work in the cylinders I4 and I6 above the walking beam comprisedof the bearing member 58 and the arms 60 and 62. t will thus be seenthat columns of water standing within the pipes IU and I2 between thepistons 42 and 68 and between the pistons 44 and 'Ill will cause thepistons in their respective cylinders to move in unison.

Formed in the cylinder I4 are longitudinally spaced ports 'I2 and 'I4which are located respectively `below and above the length of stroke of:s ,the piston 68, and formed in the cylinder I5 and extending throughthe side thereof in longitudinally spaced parallel relation are ports'f6 and 78 which are respectively located below and above the limit ofthe stroke of the piston 'I0 in s vthe cylinder I6. It will thus be seenthat water entering the cylinder I4 through the foot Valve IE thereof onthe upstroke of the piston 58 will be expelled from said cylinderthrough the port 'I2 upon the down stroke of the piston 68. .Likewisewater admitted to the cylinder I6 through the foot valve 2|) during theup stroke of the piston I0 will be expelled through the port 'I6 uponthe down stroke of the piston 'IIL Mounted adjacent the well bottom nearthe cylinders I4 and I5 is a water box designated generally 'I'I whichcomprises a front wall lll, a

`rear wall Bil, side walls 82 and top and bottom walls 84.

This water box forms a hollow rectangular structure which is separatedby a partition wall 85 into separate chambers or compartments A and B. Apipe nipple 81 communicates through the port 'I2 with the cylinder I4and extends through the wall I9 of the water box 'I1 and into thechamber B, and carried by the end fof the pipe nipple 81 within thechamber B is a .check valve 88 which is designed to admit water from thecylinder I4 into the chamber B, but

arrest the discharge of water through the nipple 31 into the cylinderI4, A .pipe nipples@ com- 'municates with the cylinder I4 through theport 'I4 and opens into the chamber A as will be readily understood uponreference to Figs. 2 and 4. A pipe nipple 90 establishes communicationbetween the cylinder I5 below the piston 'I0 and the chamber A `and isequipped with a check valve 92 (Fig. 4) which prevents the discharge ofliquid from the chamber A into the cylinder I6. A pipe nipple 94establishes communication through the port i8 between the cylinder I6'above the piston 'I0 and the chamber B so that as the pistons 63 and'I0 reciprocate in their respective cylinders I4 and I6, on the downstroke of the piston 68 in the cylinder I4, waterwill be lforced throughthe check valve 88 and into the 'chamber B, to be discharged through thenipple 94 and port 'I8 into the cylinder I6 above the piston 'IU workingtherein. Simultaneously through 4the walking beam coupling between thepistons `B8 and 1U, the upward movement of the piston I0 will fill thecylinder I5 with water through the check valve 20, so that upon the downstroke of the piston 10, the water contained in the -cylinder I6 will beexpelled through the pipe nipple 90 and check valve 92 into the chamberA. The water expelled from the chamber A will find its way through thepipe 89 and the port 'I4 into the well pipe I0 above the cylinder I4while the water which is expelled from the chamber B will find its waythrough the pipe nipple 94 into the well pipe I2 above the cylinder I6.rhe water thus expelled from the chambers A and B will form watercolumns in the well pipes I0 and I2 beneath the pistons 42 and 44 in thecylinders 22 and 24 respectively.

A water lbox designated generally 96 is carried by the well pipes I0'and I2 adjacent the cylinders 22 and 24 near the upper end of the wellhole, and comprises front and back walls 98 and I respectively and sidewalls |62, y|34 and top and bottom walls I. A horizontally extendingpartition wall |08 extends across the water box 96 between the end walls|02 and |04 adjacent the top IIlS to dene a chamber E and a partitionwall I I0 cooperates with the horizontal partition wall |03 inseparating the lower portion of the water box 86 into separatecompartments C and D. A water discharge pipe I S2 communicates with thecompartment E through the wall Iil4 of the water box 96 andcommunication between the compartment E and the compartments C and D isestablished by check valves |I4 and IIB respectively which prevent thedischarge oi water from the compartment E into the compartments C and Dwhile permitting the flow of water from the compartments C and D intothe compartment E for subsequent discharge through the discharge pipeII2. Establishing communication between the compartment C and thecylinder 22 below the piston 42 is a pipe nipple |I8 carrying at its endwithin the compartment C a check valve I2ll which prevents the egress ofwater from the compartment C into the cylinder 22 and a similar pipenipple |22 establishes communication between the cylinder 24 and thecompartment D below the piston 44, and like the pipe nipple IIS isequipped with a check valve |24 which prevents the discharge of waterfrom the compartment D into the cylinder 24. A pipe nipple |26establishes communication between the compartment D :and the cylinder 22above the piston 42 and a similar pipe nipple |23 establishescommunication between the compartment C and the cylinder 24 above thepiston 44 working therein.

In the preferred form of the invention, the pipe II has communicatingtherewith a priming valve |30 which opens into the chamber C while thepipe |22 is likewise equipped with a priming valve |32 which opens intothe chamber D. Each of these valves is equipped with a turning rod |33and a handle |34 by means of which the valves may be turned to open orclosed position.

In use, with water standing in the pipes I and I2 between the cylinders22 and I4 and 24 and I6, it will be evident that when the lever 5i) isrocked vabout its pivot 52, the walking beam at the upper end of thewell will reciprocate the pistons 42 and 44 in their respectivecylinders 2'2 and 24 so that the water within the pipes will reactagainst the pistons 68 and 'I0 to cause them to reciprocate in theirrespective cylinders I4 and I6. As the water is drawn into the cylinderI4 through its respective check valve I8, the piston 'I0 descending inits respective cylinder I6 will force the water below it into thechamber A through the check valve 92, thus causing the water standing inthe chamber A to `be discharged through the pipe 89 into the pipe II) sothat it will ow upwardly, thus creating pressure on the column of waterstanding within the pipe I0 and forcing said water through the pipenipple assises 'fiile and :cheek kvalve m trito the oompartment the endof the @cylinder 122 above 'the piston '42 "Working therein Iiilledwater, the thereinto tiaig'h the check Valve |24 'wh and its way throughthe check naive 1116 .into the eonipainaent n to discharged through the.pipe ritz.. .as the 'lasten 44 :nieves downwardly within its cylinder228., lpressure be exerted the piston .11 to downwardly and thereby thecylinder is through the onecle naive e8 to be the .'{Jit 16 80 and thevalve V92 finto 'the chamber with 'the chamber .a filled with waiter,will be evident tira/tv the fioiving through the valve 8i' will forcewater out through the 89 into 'the 'cylinder N :and .pipe dil upwardly'and into the ichamber throgiithe rppe i! 8 and chieck valve :|28 sotime water 'drawn into the cylinder i|=6 through the fcheck valve :28will be eventually discharged :ti-om the chamber .E `and discharge Spinedi 22a`t1the topo thenrell.

Like the water box 96. the water box |86 is equipped with adischarge pipe |88 through which water pumped by the pumping mechanismis discharged for subsequent use. The structure illustrated in Fig.operates in a manner corresponding to the operation of the structureillustrated in Figs. 1 through 4 inclusive with the pistons |40 and |42being actuated by the movement of the columns of water within the pipes|56 and |58.

In the further modication of the invention illustrated in Fig. 6 a pairof Well pipes |90 and 92 are provided at their lower ends with cylinders|94 and |96 respectively in which pistons |98 and 208 are mounted toreciprocate. A
